. Application filed August 25,- 1922. Serial No. 584,164.

To all whom it may concern.

Be it known that 1, JOHN R. Oniinicnon, a citizen of the UnitedStates,residing at Chicago, in the county of Cook and State of lllinois,have invented certain new and useful Improvements in Anchor Plates, ofwhich the following is a specification.

The present invention relates to anchor plates.

'More particularly the present invention relates to means for anchoringthe rails to the ties in railroad constructionand has for one of itsobjects theprovision of ellicient rail anchoring means, combined withmeans for anchoring the spikes which are ordinarily used in securingvthe rails to the ties. A further ob ect 1s to provide anchoring meansfor railroad ties which is cheap to manufacture and simple to install.

- ,A further object is to provide anchoring means which may be readilyapplied either to new construction orxto rails which are 7 already inplace;

Further objects will appear as the description proceeds.

Referring to the drawings I Figure 1 is a plan view showing part of arail, part ot a tie and one embodiment of the improved anchor plate,said anchor plate being shown in an intermediate position, occupied.when said anchor plate is being installed;

Figure 2 is a plan view similar to Figure 1 but showing the anchor platein its anchor ing position; p 7 I Figure dis a sectional view taken.along the line 3-? of Figure 2; V Figure 4 is a view in side elevationof, the structure illustrated in Figure 2; V

Figure 5 is sectional view taken along the line 55 of Figure 2; andFigures 6,7 and 8 are views of a modified form of thepresent invention.

The railroad tie is indicated by the nu-' ineral 10, while the numeral11 indicates a rail supported by said tie. 2

A great number of devices have been tried for securing rails to'theties, the most COID Inon expedient being to merely drive spikes into thetics, said spikes having overhanging heads engaging with the lowerflange of: the rail. Passage of heavy trains over the rails has theetl'ect of loosening said spikes, requiring constant attention inkeeping the rails in proper position.

The rail 11 is provided with the flanges 12-12. Underlying:thefianges1.212 is I the anchor plate 13, which anchor plate should be of toughmetal whereby to withstand severe shocks. Said anchor plate 13 comprisesthe bed portion" 14 adapted to lie upon the top of the tie 10, theillustrated anchor plate being provided with a downwardly extending pin15 on the under side of its bed portion, which pin is adapted to projectinto the tie and form a pivot point for a tie plate The bed portion 1%is recessed as indicated by the numeral'l l to avoid high spots whichwould interfere with the functions of the device. The anchor plate maybe of generalrectangular conformation in planview and will be provided,near diagonally opposed corners, with upwardly projec ing flanges 1616,.-which flanges are provided with recesses, the top walls of: saidrecesses being indicated by the numerals 17-17, As will be pointed outhereinafter, the recesses referred to are adapted to receive the headsof railroad spikes and. the walls 1-7--17 are adapted to overlie andtherefore provide abutting means to prevent the loosening of said spikesfrom the ties, The flanges 1616 have walls 1818 which act as stopsadapted to abut against the flanges 12- -12 of therail under certainconditions. Said walls 18 18 thus provide limiting means for rotarymovement, of the anchor plate relative to the rail, permitting saidanchor plate toassume the position illustrated in Figure 1, for apurpose which will be referred to hereinafter. Located in the bedportion 14; of the tie plate are the slots'19'19 which portion 14L.

road spike. which is rectangular in cross section. When the anchor plateis in. -the position indicated in Figure 1, the-angular ends of thearcuate slots 19-719 provide locating means for the railroad spike,

whereby the spike may bejdriven into the tie in a position adjacentto'the sides 01 the rail, the spikes being indicated by the nu; ineral21, each of said spikes comprisingthe shank 22 and the head 23. Theshank22 Of each spike 21 lies in proximity to the side of a flange 12 of therail, while the head 23 of each of said spikeseverlies a flange 12 7whereby to hold theralltightly in engage'' ment with the bed portion 14.Each flange V16 overlies only a part of its corresponding ar'cuate slot'19 whereby a spike may be driven into said hole in one position of theanchor plate, said spike underlying the wall 17 of flange 16 in anotherposition of said anchor plate. I

The arcuate slots 19--1'9 should be of suit? ficient length to permitthe driving of the anchor plate with a rotary movement to a positionsuch as indicated in Figure 2, in

15 'may be omitted, inasmuch as the anchor plate may be given itsdesired rotary movement without having its center of rotation fixed.

Themethod of installation and the functions of the embodiments of thepresent invention illustrated in Figures 1, to 5 will be clear ,withoutdetailed explanation. It

may be stated briefly, however, that the anchor plate will be placedupon a tie with the pin 15 embedded in said tie at the proper point topermit the necessary rotary movement of the anchor plate. The anchorplate will be placed in the position indicated in Figure 1, in which thewalls 18 of the flanges 16 lie in engagement with the sides of flanges12-12 of rail 11. End walls 20-20 of the arcuate holes 19-19 willconstitute locating means for the spikes 21-21, which spikes n'iay bedriven into the tie in proxiinity to the sides of the flanges 12-12 andoverlying the tops. of said flanges 12-12. The anchor plate may then bestruck with a sledge, being given a movement of rota tion 'to'a positioninalignment with the rail w iereby the top walls 17-17 of theflanges16-16 of the anchor plate will overlie the heads23-23 of the spikes '21.The flanges 12-12" will assume a position between the shoulders 24-24 otthe anchor plate and said anchor plate will-be securely locked inposition Spikes 21-211 will ensure this locking action. vlBy reason ofthe holding effect of flanges 16-16 it will be impos sibl'e-ior thespikcs-21-2l to work out of the ties. The upstanding walls-oiflanges16-16 also prevent the spikes 21-21 ron] bending or having theirheads forced back, which is a common occurrence in track work.The'present invention, therefore, provides means for preventing theheading or shearing off of the heads of the spikes.

WVhen it is desired to remove the anchor plate illustrated in Figures 1to 5 from be neath a rail, said operation may be accomplished byslightly raising the rail, by means of a crow bar or other means, and,the spikes 21'-21 having been removed, giving the anchor plate a blowwith the sledge whereby to drive said anchor plate to the positionindicated in Figure 1, after which the spikes 21-21 may be pried looseTi"- it is desired to install the anchor plate without removing therails from said ties, or if it is desired to remove the anchor platefrom a railwithout removing said rail, either operation may beaccomplished by lifting the rail a sufficient distance to allow the topsof flanges 16-16 to pass beneath said rail. Thelianges 16-16 need be ofonly relatively small height, so that the distance which the rail needbe lifted is relatively small.

According to the modified form of the present invention illustrated inFigures 6,

7 and 8, the locking plate is moved to or from locking position relativeto the spikes by a movement longitudinally of the rail. The anchor plateillustrated in Figures 6, 7 and 8 are indicated by the numeral 25, whichanchor plate may be of general rectangular conformation in plan view andmay be provided with the shoulders 26-26, "which. receive between themthe flanges 12-12 of the railroad rail. The anchor plate 25 is providedwith upstanding flanges 27-27 located upon the shoulders 26-26, each ofsaid flanges 27 being recessed to provide a top wall 28 and an end wall28. The anchor plate is provided with slots 29-29 extendingtheretln'ough, there being a slot 29 for each, flange 27 and the designheing'such that each flange 27 covers one end only of its correspondingslot- 29. Eachflangefli' is adapted in one longitudinal 'i'osition ofanchor plate 25 to overlie and securely hold in place a correspondingspike 30'located within the corresponding slot 29. When the anchor plateis in a different position longitudinally oi the rail, the spikes 30-30may be driven into the" tie through slots 29-29 without interferencewith flanges 27--273 The position of the anchor plate 25 permit tingdriving or"- the spikes 30-30 \vith'out interference is indicated. inFigure 6; Figure 7 represents the position oi the anchor plate 25 inwhich the flanges 27-27 overlie the spikes SO-SOa-nd securely hold samein position. Spikes 31-31 may be driven tln-ough suitable holes in theanchor plate 25 after said anchor plate has been moved to the positionshown in Figure 7, whereby to prevent said anchor plate from creepinglongitudinally of the rail. I

In installing the form of ti e: present invention shown in Figures 6, 7and 8, the

anchor plate'25 will be placed upon the tie in a position underlying therail. The anchor plate will be displaced a'short distance from itsdesired home position in a direction longitudinally of said rail andspikes -31.) will be driven through the slots 2929 at those ends of saidslots which are not covered by flanges 27-27. After the spikes 30-30have been driven into the tie, the anchor plate may be struck with asledge, moving same longitudinally of the rail to the position indicatedin Figure 7 in which the end walls Q828 of flanges 27-2T ahut againstspikes30 and top walls 28 securely hold the spikes 303O againstloosening. The flanges 2727 will also prevent movement of the headsofthe spikes 30 in a direction laterally of the rail. Spikes 3l31 maynow be inserted, to prevent creeping action of the anchor platelongitudinally of the rail.
